I am having issues resolving the SAI issues shown in the scan. I have done the following work to the car:

- Performed carbon buildup cleaning on the cylinder heads, verified passages are clear with a borescope
- Verified the pump motor is working and flowing
- Verified air pump is turning on at startup
- Checked that the hoses from the pump to the combi valves for leaks with a smoke test and also just by blocking one end and blowing into other
- Verified the combi valves are working by using a mighty vac and checking function to verify air flows when activated and no air passes when no vacuum is applied

I have also removed an O2 sensor on each cat to verify I am able to hear airflow into the exhaust. Not sure how to measure this flow, but they appear to sound like equal amounts of air is passing thru.

The car itself runs great. Starts right up, idles very smooth, runs strong. I am at a loss on what could be wrong but the code keeps coming back right after readiness is achieved.

Was the carbon cleaning performed as specified by Audi?


If not, how was the cleaning performed? And on page 2 of that PDF, what results do you get if you follow the testing info detailed there?

I wasn't able to locate the pressure washing adapters so I had found that a lot of people are using a drill bit to clear the blockage, which mine was not completely blocked. I then followed up with some brass wire brushes and then used air to clear out any dust.

The values during the said for both was 1.000
Values right after the test for both was 0.297

Test said complete and system not OK.

My educated guess is you've cleaned the "Main Secondary Port", but the separate "Single Ports" that branch off have not been cleaned. One of the nozzles with the special kit looks to be a 90deg fitting with measurements on the tube (page 8 of that TSB) so that one can locate and clean those Single Ports. A bore brush isn't going to get up in there.

What is the best method for cleaning without the $1000 pressure washer kit? I've only been able to find just the holders available for sale.

I don't know of any other method. Maybe several rounds of oven cleaner injected in there and then flushing with some water... but this is just blue sky thinking...
